Abstract
The apparatus is designed to dispense sealants and adhesives onto a workpiece in a robotic or manual application. The apparatus has a motor, a through shaft and a rotating shaft. The rotating shaft is hollow and has an off-center aperture at the end thereof through which extends one end of the through shaft. By rotating the rotating shaft, the end of the through shaft has imparted to it an orbital motion which is capable of providing a swirl type pattern onto the workpiece.
